At Astrotech's Payload Processing Facility, the solar panels on the Dawn spacecraft are stowed in preparation for Dawn's transfer to a transporter and move to the Hazardous Processing Facility for fueling. Dawn is scheduled to launch June 30 aboard a Delta II rocket from Launch Complex 17-B at Cape Canaveral Air Force Station. Dawn's mission is to explore two of the asteroid belt's most intriguing and dissimilar occupants: asteroid Vesta and the dwarf planet Ceres. Photo credit: NASA/Charisse Nahser
